When I read a word, I sometimes see a picture of the word's referent in my mind. If I read "rock," an image of a rock flickers in my head. But, when I read the word "nothing," I don't know what I see; my mind is imageless. In this group of images, I have photographed projected filmstrip leaders, areas of the film that were never exposed to light. I can't take a picture of nothing, and I have no idea what nothingness would look like. An imageless photograph is like a word without a referent. But, as far as the camera is concerned, without light there's nothing there.
